2017 Nov - First Mosaic - NGC1499

First time try mosaic.
Not process it yet ...

6 panel, each has 6 * 30min Ha sub frames

10/27/2017 UGC 2885 / PGC 213253 - How Deep from Fremont Sky ?

Always curious about how deep I can image at the very light polluted Fremont sky...

Last night, after taking several hours of Ha data on NGC1499 (California Nebula), I point my scope to a random patch near NGC1499 and take a 600sec image with L filter. Originally I was trying to see the faintest star but found an interesting galaxy in the picture.

After plate-solving and cross referencing with SkySafari, I think that galaxy is UGC 2885. I also found a discussion at CloudyNight.

UGC 2885 is 331M light years away from us but it is not the faintest galaxy in the picture. There is a tiny PGC 213253.

 SkySafari said it is a 17.1m galaxy... I am surprised this kind of object can be easily detected in a single frame image (without stacking or processing)...

Observer for about 2.5hr... Very windy and cold...
Here is the short report I wrote: http://observers.org/index.php/topic,869.0.html 

Single 30min O3 (@ 2017 CalStar Star Party) sub for Squid Nebula

I can barely see a shape here...

Very tough target. I will target on this next year !

Finally a quick process of the image we took (Adrian and me).

This is the final HaRGB

2017 CalStar Star Party -- with Adrian

This is my first ever multi-night star party. A lot of fun and good memory...

08/24/2017 NGC7331 Galaxy

Just a quick shot from my front yard. Want to see how much LP would I get with L filter...
5min x 24
SBIG 8300 with SVQ100

08/21/2017 Partial Eclipes

Not able to go to Oregon is killing me ;-(
We drove to a supermarket parking lot at Palo Alto and enjoy the partial eclipse...

08/12/2017 Meteor Shower

Take family out to see the meteor shower... haha...

Stacking Effect -- single frame vs. 25 frames

Test GIF -- Time-Lapse from William Hill

06/03/2017 Kickoff Deep Crescent Nebula Project -- Ha First

Plan to collect total 12hr Ha (24 subs with 30min each)...
Will take 3 nights ... from 12am to 5am

Use SGP Pro autofocus... works great out of box...

Take 30 flat subs every morning...
